Anyway, I bought a pair of black flats that will hopefully not rub my feet raw. (I do realize that most 5'1" women would wear shoes with a heel, but I don't like them. And, anyway, the shoes with heels were more expensive.) I walked around the store a couple of times to test them out, and they seemed fine -- though a bit big, of course -- so I hope I'll be okay. At least they don't fall off like the pair I wore yesterday.
I had planned to go shopping for jeans that fit after I bought the shoes, but shoes are much more expensive than I expected. I bought one of the less expensive pairs of work-appropriate shoes in the store, and I still spent $50. I feel ripped off -- they're just shoes, for god's sake! they aren't made of gold! -- but I needed them for work, so it wasn't really a choice. The shoes that were even less expensive (by about $10) weren't even close to my size.
So I'll continue wearing jeans a size too big for a while longer. Oh well. The work stuff was more urgent.
I hate shoe shopping. Argh.
